In reporting its earnings, Apple said it sold 3.36 million Macs, representing a 33 percent unit increase over the year-ago quarter. The company also sold 8.7 million iPhones in the quarter, representing 100 percent unit growth over the year-ago quarter.

Apple sold 21 million iPods during the quarter, representing an eight percent unit decline from the year-ago quarter.

Peter Oppenheimer, Apple’s CFO, said the company generated $5.8 billion in cash during the quarter. Looking ahead, Oppenheimer said Apple expects to report revenue of $11.0 billion to $11.4 billion in the second fiscal quarter.
